Interim Biogeographic Regionalisation for Australia (IBRA), Version 7 (Regions) - States and Territories

Interim Biogeographic Regionalisation for Australia (IBRA) version 7.0 represents a landscape based approach to classifying the land surface of Australia. 89 biogeographic regions and 419 sub regions have been delineated, each reflecting a unifying set of major environmental influences which shape the occurrence of flora and fauna and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.0 data consists of two datasets. IBRA bioregions, which is a larger scale regional classification of homogenous ecosystems, and sub regions, which are more localised. IBRA Version 7.0 is the result of both significant changes to certain IBRA 6.1 boundaries, plus refinement of other boundaries due to better data availability amongst some states and territories, and alterations by the states/territories along state borders. The updated boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. In this respect refinements were carried out to all mainland jurisdictions with significant changes in Queensland and South Australia. In addition the dataset was also updated to more closely conform to the Geoscience Australia 1:100K State borders, and a standard coding/naming convention introduced (for both regions and sub-regions) resulting in differences to both names and codes used in earlier IBRA Versions.\nVarious sources were used to delineate islands - these included the GA100K Admin layer plus the Australian Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and the GA Commonwealth Fisheries 2006 dataset.CC - Attribution (CC BY)\nData to be available in the Public Domain under Creative Commons by Attribution Licensing Agreement. \nMore information can be found here: http://creativecommons.org/licenses/by/3.0/au/deed.en\nUsers must attribute the Australian Government Department of the Environment and Energy as the data provider.

澳大利亚临时生物地理区域划分（Interim Biogeographic Regionalisation for Australia, IBRA）7.0版采用基于景观的方法对澳大利亚地表进行分类。该划分已划定89个生物地理区域与419个次级区域，每个区域均体现了一系列统一的主要环境影响因素，这些因素塑造了澳大利亚及其海外领地（南极洲除外）范围内动植物的分布格局，以及它们与物理环境的相互作用。
IBRA 7.0版数据集包含两类数据：一类为IBRA生物地理区域，即针对同质生态系统的大尺度区域分类；另一类为次级区域，属于更精细化的局地划分单元。
IBRA 7.0版的形成，既包含对部分IBRA 6.1版边界的重大调整，也因部分州和领地获取了更优质的数据而对其他边界进行了优化，同时纳入了各州/领地沿州界做出的修改。更新后的边界由联邦、州和领地的自然与保护机构共同确定。在此框架下，所有大陆辖区均完成了边界优化，其中昆士兰州与南澳大利亚州的调整幅度最为显著。此外，该数据集还进行了更新，以更贴合澳大利亚地球科学局（Geoscience Australia）1:10万比例尺州界数据，并引入了适用于区域与次级区域的统一编码与命名规范，这使得相较于早期IBRA版本，本次更新后的名称与编码均发生了变化。
岛屿的划定参考了多种数据源，包括GA100K行政图层、澳大利亚海事边界数据集、存储于ERIN的珊瑚海数据集，以及GA 2006年联邦渔业数据集。
